Band pass filter glass is a kind of narrow bandwidth, short wave and long wave have a clear cut of the glass, as shown in figure. Their spectral properties are represented by the maximum transmission ratio (TM) and its wavelength (M) position, the cutoff wavelength, the wavelength cutoff wavelength, and the half width. The maximum transmittance of the glass with glass is half of the difference between the wavelength of 1 and 2 (1- 1). The wavelength cutoff wavelength is at the peak value of the short wavelength, and the transmittance is equal to zero. The glass is long long wavelength cutoff in the peak wave side, transmission ratio is equal to zero wavelength, some varieties, in the long wavelength side glass transmission ratio of less than zero, the transmission of a certain wavelength than said. With the glass to the first letter of the alphabet DTB to name, the transmission ratio of the maximum value of the wavelength position as their serial number.
